BACKGROUND Technical Field

The disclosure relates to transmission methods and devices in wireless communication systems, and in particular to a communication method and device supporting data transmission over unlicensed spectrum.

Related Art

In 5G systems, Enhance Mobile Broadband (eMBB) and Ultra Reliable and Low Latency Communication (URLLC) are two typical service types. A new Modulation and Coding Scheme (MCS) table has been defined for URLLC services in the 3rd Generation Partner Project (3GPP) New Radio (NR) Release 15.

In order to support URLLC services of higher requirements, for example, higher reliability, lower latency (0.5-1 ms), etc., the 3GPP Radio Access Network (RAN) #80 session had approved a Study Item (SI) of URLLC enhancement of NR Release 16, in which enhancements to scheduling/Hybrid Automatic Repeat reQuest (HARQ)/Channel State Information (CSI) timeline are a key point to be studied.

SUMMARY

The inventor finds through researches that applications having low-latency requirements need to feed back a HARQ/CSI quickly while applications having no low-latency requirements may feedback a HARQ/SCI slowly; therefore, how to configure a HARQ/SCI feedback in view of different latency requirements is a key problem to be solved.

In view of the above problems, the disclosure provides a solution. It should be noted that embodiments of the disclosure and characteristics of the embodiments may be mutually combined arbitrarily.

The disclosure provides a method in a User Equipment (UE) for wireless communication, wherein the method includes:

-   -   receiving a first signaling;     -   receiving a first radio signal in a first time window; and     -   transmitting a feedback on the first radio signal in a second         time window.

Herein, the first signaling is used for determining time-domain resources occupied by the first radio signal; a first time-domain deviation is a deviation in time domain between the second time window and the first time window; when the first signaling carries a first identifier, the first time-domain deviation is one of K1 first-type candidate deviation(s), and K1 is a positive integer; when the first signaling carries a second identifier, the first time-domain deviation is one of K2 second-type candidate deviation(s), and K2 is a positive integer; the first identifier is different from the second identifier, and at least one of the K2 second-type candidate deviation(s) is different from all of the K1 first-type candidate deviation(s).

In one embodiment, the problem to be solved by the disclosure is: how to enhance the scheme of configuration of Hybrid Automatic Repeat reQuest ACKnowledgement (HARQ-ACK) feedback latency in view of the lower-latency requirements in NR Release 16.

In one embodiment, the problem to be solved by the disclosure is as follows: in NR Release 15, the configuration of HARQ-ACK feedback latency may be indicated through Downlink Control Information (DCI) (PDSCH (Physical Downlink Shared CHannel)-to-HARQ_feedback timing indicator field in DCI format 1_0 or 1_1) or configured by Radio Resource Control (RRC) (when the PDSCH-to-HARQ_feedback timing indicator field is a 0 bit in DCI format 1_1). The method of indication through a DCI is to select one latency value from one HARQ-ACK feedback latency range configured by an RRC, while the method of configuration through an RRC is that the RRC configures one HARQ-ACK feedback latency. To support a HARQ feedback with a lower latency in NR Release 16, how to enhance the above method of DCI indication or the above method of RRC configuration is a key problem to be solved.

In one embodiment, the essence of the above method is that: the first signaling is a DCI signaling for scheduling a PDSCH, the first radio signal is a PDSCH scheduled by the first signaling, the feedback on the first radio signal is a HARQ-ACK, the first time window is a slot in which the PDSCH is located, the second time window is a slot in which the HARQ-ACK is located, the first time-domain deviation is a feedback latency of the HARQ-ACK relative to the PDSCH, and the first identifier and the second identifier are two different Radio Network Temporary Identifiers (RNTIs) used for CRC scrambling of the DCI. If detected that the DCI is scrambled with the first identifier, the feedback latency of the HARQ-ACK relative to the PDSCH belongs to the K1 first-type candidate deviation(s); if detected that the DCI is scrambled with the second identifier, the feedback latency of the HARQ-ACK relative to the PDSCH belongs to the K2 first-type candidate deviation(s). The adoption of the above method has the following benefits: the RNTI used for scrambling the CRC of the DCI is associated to a HARQ-ACK feedback latency range, thus the HARQ-ACK feedback latency range may be determined implicitly by identifying the RNTI; on one hand, for the case of selecting one latency value from the HARQ-ACK feedback latency range through the DCI signaling, the above method avoids the case that more bit overheads are introduced into the DCI to support a lower latency; on the other hand, for the case of indicating the HARQ-ACK feedback latency through the RRC signaling, multiple HARQ-ACK feedback latency ranges associated to the RNTI are configured, which solves the problem that different services have different requirements on latency.

For the case of selecting one latency value from the HARQ-ACK feedback latency range through the DCI signaling, the disclosure avoids the case that more bit overheads are introduced into the DCI to support a lower latency.

For the case of indicating the HARQ-ACK feedback latency through the RRC signaling, the disclosure configures multiple HARQ-ACK feedback latency ranges associated to the RNTI, which solves the problem that different services have different requirements on latency.

In FIG. 3 , the radio protocol architecture of a UE and a base station (gNB or eNB) is illustrated by three layers, which are a Layer 1, a Layer 2 and a Layer 3 respectively. The Layer 1 (L1 layer) 301 is the lowest layer and implements various PHY (physical layer) signal processing functions. The L1 layer will be referred to herein as the PHY 301. The Layer 2 (L2 layer) 305 is above the PHY 301, and is responsible for the link between the UE and the eNB over the PHY 301. In the user plane, the L2 layer 305 includes a Medium Access Control (MAC) sublayer 302, a Radio Link Control (RLC) sublayer 303, and a Packet Data Convergence Protocol (PDCP) sublayer 304, which are terminated at the eNB on the network side.

The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides header compression for higher-layer packets so as to reduce radio transmission overheads. The PDCP sublayer 304 provides security by encrypting packets and provides support for UE handover between eNBs. The RLC sublayer 303 provides segmentation and reassembling of higher-layer packets, retransmission of lost packets, and reordering of lost packets to as to compensate for out-of-order reception due to HARQ.
